き、型枠を締付けるとき締付杆による締付け過ぎが防止
されて作業し易い上に、横ばたを堰板に確実に締付け固
定してコンクリート壁を正確に形成し得る。(1) When assembling the formwork by combining vertical and horizontal flaps on the outside of the barrier plate, the lateral flap receiver is held by the clamping rod of the formwork. Even if the nut is strongly screwed in, it prevents the weir plate from being pulled out to the outside by the tightening rod and bulging and deforming even when the nut is strongly screwed in.
The weir plate can always be kept flat and the formwork can be firmly tightened, and when tightening the formwork, overtightening is prevented by the tightening rod and work is easy, and the horizontal plate is securely fastened to the weir plate. The concrete wall can be accurately formed.
更に、堰板の外側に横ばたのみを組合わせて型枠を組立
てる場合は、横ばた受け具によって型枠を堅固に組立て
ることができ、堰板の外側に縦横のばたを組合わせる場
合と、横ばたのみを組合わせる場合の両方に兼用し得て
作業上至便である。Furthermore, when assembling the formwork by combining only the horizontal flaps on the outside of the barrier plate, the horizontal and horizontal flaps can be firmly assembled on the outside of the barrier plate by using the horizontal flap receivers. It can be used both in the case and in the case of combining only the horizontal plate, which is convenient in terms of work.
（２）締付杆、横ばた受け具、ナット、押え座金、ナッ

して作業能率を向上する。(3) Since the upper seat piece is short and the lower seat piece is long, the laterally-laid receiver always stands still with the upper and lower seat pieces facing in the vertical direction. Therefore, when inserting a lateral plate from above and below between the vertical plate and the joint surface of the multiple press washers, or between the barrier plate and the joint surface of the multiple lateral flap receivers, respectively, The insertion operation can be done easily and quickly, saving labor and improving work efficiency.
（４）横ばた受け具は、上方座片が短かくて材料を節減
できる。(4) In the sideways receiving member, the upper seat piece is short, so that the material can be saved.
（５）構造が簡単で容易安価に製作し得られ、作動は軽
快円滑である。(5) The structure is simple and can be manufactured easily and inexpensively, and the operation is light and smooth.
